Camera Module Optical Center Stability via Dynamic Bracket
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing camera modules in terminals are prone to optical center displacement due to external forces, such as shaking or falling, which reduces the quality of pictures taken by the secondary camera module.
Innovation Solution
A camera module design featuring a first camera, a second camera, a light guide component, and a bracket that surrounds the second housing, with the bracket including positioning parts to securely fix the camera module to a circuit board, ensuring the optical center remains stable and aligned.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the secondary camera module is fixed by securing its bottom part to a circuit board, then the device structure is simple and easy to manufacture, but the optical center of the secondary camera module is prone to displacement under external forces such as shaking or falling
Solution Approach 1:
The patent introduces a movable connection mechanism between the secondary camera module and the circuit board, allowing the camera module to move relative to the circuit board while maintaining electrical connections. This dynamic structure enables the optical center to return to its original position after displacement caused by external forces, resolving the contradiction between reliability and structural simplicity.
Solution Approach 2:
The patent employs a flexible circuit board as an intermediary element between the secondary camera module and the rigid circuit board. This flexible intermediary absorbs mechanical stress and allows relative movement while maintaining electrical connectivity, thus protecting the optical center stability without significantly complicating the overall structure.
2Manufacturing precision
If the secondary camera module is firmly fixed to prevent displacement, then optical center stability is improved, but the device becomes more complex and difficult to manufacture
Solution Approach 1:
The movable connection mechanism allows the secondary camera module to dynamically adjust its position, automatically returning to the correct optical alignment after displacement. This eliminates the need for complex precision fixing structures, maintaining manufacturing precision while simplifying the assembly process.
Solution Approach 2:
The patent designs a self-aligning mechanism where the secondary camera module automatically returns to its correct optical position after being displaced by external forces. This self-correcting feature maintains optical center alignment precision without requiring complex manual adjustment or precision fixing structures during manufacturing.

AI summary
A camera module includes a first camera, a light guide component, and a fixing component. The light guide component is configured to collect light from outside and guide the light into the first camera. The fixing component is disposed on a periphery of the first camera and the light guide component. An optical center of the first camera is coincident with an optical center of the light guide component.
